SPECIFICATION forming part of Letters Patent No. 772,920, dated October 25, 1904.

Application filed March 30, 1904. Serial No. 200,789. (No model.)

To @ZZ whom if may cori/cern,.-

Be it kn-own thatwe, JACOB BREWER, residing at Hazleton, and DANIEL HEAVENER, residing at Nescopeck, in the county of Luzerne and State of Pennsylvania, citizens of the United States, have in vented a new and useful Window-Sash Fastener, of which the following is a specification. Y I

- acter which may be inexpensively manufactured and easily applied to any ofthe ordinary constructions of window frames and sashes. l l

With these and other objects in view, which will appear as the nature of the invention is vbetter, understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forminga part of this specification, and .in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily-'limited thereto as various changes in the shape, proportions, and general assemblage of the parts may-be resorted to without departing from the princip le 0f the invention or sacrificing any-of its advantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the invention andthe claims made therefor.

In the drawings thus employed, Figure-1 is a View of the inside ofa window-frame with portions of the upper and lower sash in section therein.v Fig. 2 isa transverse section on the line 2 2 of Eig. 1. Fig. 3 isa transverse section-'on theline 3 3 of Fig. 1. Eig. 4 is a perspective view of'one of the supplemental weights detached.

In applying the improved device the ordinary window-frame 10 is employed,. having lthe meeting-rail portions of the sash when closed.

Within a gap formed for it in the `partingstrip 12 adjacent to the meeting-rails of' the sash when closed is a casing 17, having sockets in its ends to receive andsupport the adjacent ends of the severed parting-strip and? with a central transverse recess 18, and in the frame 10 in transverse alinement with the recess 18 is a channel 19, in which a bolt 20 is slidably disposed, one end of the bolt being bent to pass through the recess 18, as at 21,

for engagement -with sockets 22 in the inner face of the Vupper sash 14 when the bolt is protruded and with the other end, 23, of the bolt bent for passage through the larger cas-` ing 16 and terminating in a guide 211 through van aperture in the outer end of the casing.

vsame vand is held normally in engagement 25, as will be obvious.

Located in the casing 16 beneath the bolt with the recesses 22 in the sash 14 by the spring 20 is another and shorter bolt, 26, for engagement with spaced sockets 27 in the inner face of the lower sash 15, the sockets being entirely covered by the inside stop 13 and casing16. The bolt 26-is also provided with a spring 28, operating similarly to thespring 25 on the bolt 20.

The bolts20 26 are provided, respectively,

, with studs 32 and 33, extending through longitudinal slots in the casing 16 and provided with operating-leversv 34 35, exteriorly of the casing.

The levers 34 35 are preferably pivoted to one common pivot-pin 36 and are curved and extend in opposite directions for engagement with the studs 32 33 and are provided with linger-grips 37 38 and longitudinal slots to embrace the studs, so that the levers will not fall away from the studs when not in action. By this simple means it is obvious the bolts 2O 26 may be independently actuated and either sash raised or lowered to any desired extent without interfering with the other sash.

rlhe weights for the sash are represented at 39 4() of the usual form and adapted to just balance the sash; but in the improved device herein described supplemental weights 4l 42 are added to each to overbalanee the weights of the sash and cause them to be automatically elevated when released, the upper sash being thus automatically closed and the lower sash automatically opened when the loclingbolts are released. The supplementary weights are formed in two sections divided longitudinally with internal grooves for engaging the weight-cables 43 44 and bound thereon, as by wire binders 45 46. By this simple means the supplemental weights may be quickly attached to the weight-cables already in use in buildings, which is a great advantage, as will be obvious.

The bolt 2O for the lower sash will be inclined on one side at its inner extremity for engagement with the sockets when the sash is moving in one direction and which will freely slip over them when moving in the opposite direction; but the extremity of the upper bolt 20 will be square-ended, so that the lower sash may be freely moved downwardly when required without regard to the presence of the bolt 26; but the upper sash is firmly held from movement in either direction.

It will be obvious that a very simply-constructed and easily applied and operated device is produced which may be readily applied to the frame and sash and by means of which the sash can be very easily handled and opened or closed to any desired extent and firmly held at any desired point. It will also be evident that the sash cannot be surreptitiously opened from the outside, and the device therefore forms a burglar-proef fastening, rendering it safe to leave the sash partially raised for ventilation.

The recesses for the bolts may be disposed at as frequent points as required, but will generally be located about two inches apart.

The casings 16 and 17 will be secured by suitable screws and may be plated or otherwise ornamented or protected, so that they present a pleasing appearance.

Having thus described the invention, what is claimed isl. The combination with a window-frame and upper and lower sashes mounted therein, of a keeper carried by the upper sash, an endwise-movable bolt working in the windowframe across one upright edge of the lower sash and having its opposite ends ollset out wardly from the window-frame, the outer offset end being formed for engagement with the keeper, a casing carried by the frame and housing the inner offset end of the bolt, a spring within the casing and engaging the bolt to yieldably hold it at its outer limit, a projection carried by the bolt and working in a slot in the easing, and a controlling-lever fulcrumed upon the easing and having a slot receiving the projection.

2. A sash-lock comprising a casing, an endwise-movable bolt having its opposite ends offset laterally in the same direction with one offset end working in the casing and provided with a projection working in a slot in the easing, and a lever fulcrumed externally upon the casing and provided with a slot receiving the projection.

3. A sash-lock conn'n'ising a casing havingl upper and lower substantially horizontal slots, a bolt projected through the easing and having a projection working in the lower slot, another endwise-movable bolt having its opposite ends offset in the same direction with one end working in the casing and provided with a projection working in the upper slot of the casing, and reversely-disposed levers mounted upon a common fulcrum located between the two slots and provided with longitudinal slots receiving the respective projections.

In testimony that we claim the foregoing as our own we have hereto aliixed our signatures in the presence of two witnesses.
